Cyberham,
It is really interesting that you were "not able to receive any signal from the SL2" which was mounted beside your existing, ("main") Digiwave. If you added SL2 on the "East" side of Digiwave, and - assuming - Digiwave was receiving 97 W, you should be able to catch signal from SL2 on which signal from 101 W was focusing - providing, the SL2 was also about 5/8" higher than Digiwave. But your goal was, I believe, to compare these two LNBs on the same source. However, one LNB, sitting in privileged pure focus, would have advantage over other LNB, sitting in a "focus" with a little coma. Therefore, swapping the LNBs in the same "seat" would be the best test, what you did. I realize that swapping LNBs on a 8-foot tower is not much fun, anyway. Cheers, polgyver
